    About this role

    As a Machine Learning Research Engineer, you'll drive research that teaches models what great feels like across domains such as model personality and behavior, UI design, multi-modal generation, and writing tone. It's a hard, ambiguous, and (very) cool problem space.

    You'll own full-stack research: experiments, training runs, data and eval pipelines, and publishing results. You'll develop Taste's internal research and proprietary models while collaborating directly with AI labs on frontier projects.

    What You'll Do

    • Train reward models, classifiers, and verifiers for subjective domains (e.g. design, writing, visual style).
    • Develop frontier evaluations and benchmarks for subjective domains.
    • Run post-training experiments on open-source models to test new data formats and post-training techniques.
    • Collaborate with AI labs and creative experts to design pilots and experiments around taste.
    • Own the end to end pipeline.
    • Publish blogs and whitepapers.

    You Might Be a Good Fit If You

    • Are obsessed with taste and want a world with less AI slop.
    • Have experience in ML research, Applied ML or ML research engineering, especially in post-training/fine-tuning large models (SFT, RLHF, DPO). Experience with LLM/diffusion models is required.
    • Think like a researcher, move like an engineer. Are creative, scrappy, and comfortable operating in ambiguity.

    Salary: $200K - $350K

    Equity: 0.25% - 1.5%
